Watching Donny become a bit frustrated that he wasn't tickling was funny. "Maybe a little." And mostly he had never been very ticklish. So, either way, it worked in his favor. "Sorry, got nothing for you here. I can fake it if you'd like." He gave her a fake laugh and a little wiggle since that's all she was going to get out of that.
"Who in their right mind would wear glitter underwear? That sounds like it could be itchy and messy." Although, now he was thinking he should get her glittery underwear just to see her reaction to them.
"Your jaw is going to be pretty sore...maybe you shouldn't gnaw through them, huh?" he said, playing along. "Mm, yeah, you're getting there."
